Dar es Salaam’s water supplies need stronger, more flexible management to meet SDG6
Meeting the Sustainable Development Goal of access to drinking water (SDG6) is a significant challenge for growing cities like Dar es Salaam, where currently only half of the population of 5 million has secure and safe supplies. The city lies at the bottom of a small catchment. River flows are highly seasonal and upstream demands for dry season agriculture are increasing. Demand for drinking water, irrigation and environmental flows compete with one another, and operate at different institutional and spatial scales. Hydrological modelling suggests the city’s plans for expanded supply will fall short unless supply and extraction regulators work jointly to use all the available water resources sustainably and flexibly.
